Relay boards for remote control?

Hi
Can anyone tell me what would be the most popular rs232 (or USB) relay board for use in computer control of a k3 setup? I use the canakit 4 relay USB board. Are there others?
Thanks

I've not tried these myself, but bookmarked them a while back, as they
looked possibly interesting:

They have some with ethernet built in too....

Re: Relay boards for remote control?

I have used the denkovi 16 relay set and the 8 relay set with ethernet access to design and build a controller which automatically selects either my normal antenna for each band or an alternate antenna for that band. I use the K3's BCD outputs to determine the band, and a arduino programmed to decipher which relay to kick in. The unit also will switch my two radios over to a dummy load (all done through relay switching of 12 volt lines). I use the ethernet module to control the relays when I have a radio in my living room (as opposed to the one in my shack).
With the denkovi relays, you can choose from ethernet controlled, USB control, or serial control, and they have some excellent software for each module. The ethernet module has a built-in web site which you can set up to access from your computer.

I have not found any negatives with these units. They are well-built and well documented.

Re: Relay boards for remote control?

Hi,
I wondering about the USB versions. They have a caution in the docs about a power cycle, which causes the relays to switch several times during power up of the computer. This could cause some undesirable effects I would think.
The serial and Ethernet do not seem to be affected. And, what is the difference between the serial versions which use a USB connector anyways?
Any ideas? They do look good, with relays supporting 15a at 120

There are others. I use a SERDO8R purchased from EasyDAQ.com. It has an
RS232 interface and eight DPDT relays on a PC104 stackable profile. Current
price is $81, which I think is a bit much, but it is a well-constructed
board and is supported by National Instruments LabVIEW drivers (which I why
I have it). For $97 you can order it with eight programmable digital inputs
or outputs that operate in parallel with the eight relays.

I think Denkovi has a broader range of products with more interfaces and
lower prices. If I needed another relay interface I would buy the Denkovi
USB Eight Channel Relay Board ForAutomation, currently selling for $41, but
I have no experience with them.

Re: Relay boards for remote control?

Yup same ones. Looks like the Ethernet ones are good for remote access. You can turn on whatever you want as long as the relay board is powered.
Thanks for all the replies.

Another source is http://www.j-works.com/index.php. They have a broad
product line. I've used one of their devices (USB to 4 SPST relays) for
years with my logging program CQPWIN, instead of using serial or parallel
port outputs for various rig control functions (e.g., PTT, Radio switching,
etc.). Never had a problem.
